Pet Organics No Go!® has been developed to help you housebreak your pet. No Go!® is not a repellent. When sprayed on the soiled area, No Go!® will eliminate the urine scent so your pet will not re-urinate in that area. Works great on indoor plants and Christmas Trees too! No Go!® contains no harsh chemicals. Safe to use on almost all fabrics, however, before using product test on small inconspicuous area of surface.
